Title: Method and apparatus for the manufacture of belting
Inventor: HOGG WILFRED HENRY
IPC: B29D29/00
Filed: 1959-01-01
Abstract: <PICT:0923713/IV(a)/1> Mechanical belting, particularly narrow belting, is made by immersing two or more layers of woven fabric or other reinforcement material in spaced relation in a trough containing a liquid intermediate elastomer composition, bringing the layers together in the trough, removing the coated layers and completing the condensation or polymerization of the elastomer. Fabrics preferably employed are those made of thermoplastic fibres such as polyethylene terephthalate, and these are slit longitudinally with a heated knife without severing the warp threads, fused edges being thus produced which are coated with, and protected against abrasion by, the coating composition.  Preferably polyurethanes are employed as the elastomers, alternatives being vinyl plastisols or polysulphide condensation products.  Examples of coating materials and their uses are-(1) a mixture of predried polyethylene adipate of molecular weight about 2,000 and naphthalene 1:5 diisocyanate, catalysed by butane 1:2 diol, allowed to gel at room temperature after coating, and then stoved at 110 DEG C.; (2) a prepolymer prepared from polytetrahydrofuran and an aromatic diisocyanate mixed with methylene bis-o-chloraniline as accelerator held at 110 DEG C. for 20 minutes and then treated as in (1).  The apparatus used, Fig. 2, comprises a trough 10 containing the pre-elastomer composition C and guide bars 12, 13 for three strips A, B, C, of belting fabric. The coated strips are passed between doctor blades 14 in a slot 11 in the base of the trough and are then compressed between adjustable rollers 15 and subsequently removable cover sheets E, F, e.g. of regenerated cellulose, polythene, polytetrafluoroethylene or polyethylene terephthalate.  In a modification two fabric strips are passed downwardly into a trough, around closely adjacent guide bars, and up in face-to-face relation through a central slot having adjustable doctor blades.  Bars in the trough at right angles to the guide bars prevent laleral displacement of the fabric strips.

Abstract: 387,485. Drawing. OLDFIELD, T., 37D, Beverley Terrace, Boothtown Road, Halifax, Yorkshire. Jan. 5, 1932, No. 270. [Classes 83 (ii) and 83 (iv).] Dies ; making golf clubs.-Tubes especially for golf-club handles are tapered by rotating them between segmental dies 1, 2 each having a peripheral groove 3 of semi-circular cross section and gradully decreasing in diameter according to the taper to be produced, the dies being slowly rotated in contact with the work and traversed along it. The dies are supported on vertical shafts on a saddle 8 movable on longitudinal guides 9. A chuck 29<A> for supporting the work is mounted in a stationary headstock 29, and is rotated from a shaft 28, which also rotates the dies through gearing, a shaft 21, gears 20, 19, a shaft 18, worm 17, and further gearing to drive shafts 4, 5, and effects the longitudinal movement of the saddle through a gear train, a shaft 39, a worm 40, a gear 41, and a gear 42 meshing with a rack 43. The rotation of the dies and the saddle traverse are automatically stopped when a projection 51 strikes a stop 50, first moving a rod 45 to the right to disengage gear 20 from gear 19 by a lever 48 and, when this lever strikes an abutment 46, moving a rod 52 to the left so that a recess 55 thereon comes beneath a projection 54 on the housing of the worm 40 to permit it to drop from engagement with its wheel 41. Manual means for returning the carriage, rotating the dies, and resetting the stop devices are included. The tapering may be effected in one operation, or the second half of a tube one inch in diameter may first be tapered, for example, by the half of the dies producing a taper varying from one inch to three-quarters of an inch, and then the whole tube tapered to the minimum diameter of one-half an inch, the dies and tube being marked in equal divisions in such successive operations. Two or more sets of dies may be carried in one machine for simultaneous operation, and each die may have several grooves in its periphery for different tapers. The rotation of the dies may be stopped while their longitudinal traverse continues, to produce tubes of irregular taper.

Title: Accelerometer
IPC: G01P15/08
Filed: 1960-01-07
Abstract: 939,976. Measuring acceleration electrically. GLOBE INDUSTRIES Inc. Jan. 7, 1960 [April 22, 1959], No. 667/60. Class 40 (1). An accelerometer comprises a quantity of conducting liquid in a cylindrical chamber which is rotated about its axis so that the surface of the liquid is forced into a vortex, whose lowest point is sensed by a probe, the speed of rotation being automatically controlled to maintain this depth constant with varying axial acceleration, whereby the angular velocity is indicative of the axial acceleration, and is measured by a pulse frequency obtained from a rotating switch at one end of the chamber. As shown (Fig. 1), a motor 2 rotates an insulating, cylindrical member 27 so that a conductive liquid 22 in a cavity 20 is forced into a vortex 24. The bottom of the vortex is sensed by an axial probe 54, which feeds a negative bias from lead 14 via the liquid 22, pin 21, disc 26, brush 28 and lead 38 to the base of a transistor 40, making the transistor conductive and allowing energization of motor 2. The motor speed rises until the bottom of the vortex leaves the probe 54, whereupon the motor circuit is broken, and the motor slows down. Thus the motor hunts about the speed which just produces contact between the probe 54 and the liquid 22, and changes in axial acceleration produce corresponding changes in the angular velocity of the motor to maintain this condition..The motor speed is measured by a brush making contact with the edge of the end disc 29 which is divided into, e.g., five conducting segments, thereby producing five pulses per revolution. The frequency of the pulses, fed along lead 80, is measured to indicate acceleration, and integrated to determine velocity. In another embodiment (Fig. 4, not shown), the probe 54 senses the side of the vortex. Specification 850,945 is referred to.
